“…The solution of the associated Schrödinger equation is analytically exact, thus allowing us to find the eigenfunctions and, with the appropriate boundary conditions, to determine the energy eigenvalues for each region of the potential. As the transfer occurs in pairs of wells, from one well to its neighbor, the solution is obtained by breaking the potential in four sets of asymmetric double wells, where each double well is regarded as the junction of two single ones, and each well confined by an infinite barrier on one side and a finite barrier on the other side [21]. Thus, the physical problem to be solved involves an asymmetrical bistable well with respect to the depths V 0 and V 1 of the two wells involved, where V 0 < V 1 , as shown in Fig.…”
